Influència de l’altura, la distància dels tubs al carrer, l’amplada del carrer, el trànsit i la densitat de trànsit sobre la concentració de NO2; Influence of the height, the width of the street, the traffic and the density of vehicles on the NO2 concentration

During the first decades of 20th century has contemplated an important increase of the
coronary diseases, that stimulated this research for the reasons mentioned above. In
1978, in order to investigate this phenomenon, Josep Trueta Hospital of Girona began a study called REGICOR. In the 20th century also has contemplated an increasing
problem of pollution of the urban atmospheres, this did that different scientists were studying the relations between the coronary diseases and the atmospheric pollution in urban areas (Godish, 1997; Krupa and Legge, 2000; Brook et at., 2004 and Krewski et at., 2004). The project is placed in the context of the first study realized in Spain that investigates the effects on the health of the atmospheric pollution (REGICOR 2000-AIR). In the project one tries to investigate the influence of different factors (distance of the pipes to
the street, width of the street, traffic and density of traffic) on the atmospheric pollution of the cities of Girona and Salt, in order the possible better(best) thing is able to characterize the exhibition to atmospheric pollution. For this purpose the NO2 will be in use as scoreboard of atmospheric pollution and several points of the sample were selected in both cities where they will put on captators of NO2 for the measurement of the above mentioned pollution. Later, and by means of a statistical analysis, it will be possible to determine the influence of the factors in the variation of concentration of NO2 in the selected area.
